AppDynamics End User Monitoring (EUM) provides visibility into application performance from the client's perspective. This includes Browser Real User Monitoring (RUM), Mobile RUM, and IoT Monitoring. A core capability of Mobile and IoT RUM is to capture and analyze network requests made from the end-user's device. This allows operations teams to identify and troubleshoot the slowest network requests, crashes, and other errors, thereby locating the root cause of performance problems experienced by the user on their specific device.

A. This describes the function of AppDynamics Network Visibility, which focuses on monitoring the network transport layer and its impact on application performance, not the client-side experience itself.

B. This is a capability of AppDynamics Server Visibility (or Infrastructure Visibility), which monitors the health and performance of servers, including CPU, memory, and running processes.

D. This is the primary function of AppDynamics Database Visibility, which provides deep insights into database performance, including slow queries and resource contention within the database tier.
